FRANK s. cnownnn, or TOLEDO, OHIO, assreno'a T was EDWARD N;- armies conPANY, or 'rornnno, onia-a-eonreaa'rron on 01 E101 LIGHTING FIXTURE.

Application filed. January My invention relates more particularly tothat class of lighting fixtures which are used on porches or exteriorsof buildings. It

will be apparent from-the hereinafter contained description that it isequally useful which macl'iine work is practically eliminated and whichis so constructedthat it will shed water and greatly decrease the amountof snow which would lodge on the fixture,

- and to provide aconstruction in which, that even if snow does lodge onit when it melts, it will be unable to interfere with the opera tion ofthe fixture.

My means of accomplishing the foregoing objects may bemore'readi'lyunderstood by having reference to theaccompanying drawingswhich are hereto annexed and made a part of thisspecification in whichFig. 1. is a front elevation of a lighting tixture constructed inaccordance with myimprovement.

Fig. 2 is a vertical'sectional viewtaken on the line 2-2 in Fig. 1 inthedirection indicated by the arrows.

Fig. 3 1s a cross sectionalview taken on the line 33 in Fig. 2 in thedirection indicated by the arrows.

Fig. 4 is a View of the plate, the lamp support being omitted.

Similar reference numerals refer to similar parts throughout the entiredescription. As shown in the drawings, my invention comprises a plate 1,which is provided with an aperture 2, and a depression or recess 3,which is formed with a downwardly depending V shaped portion '41-, andtwo laterally extending horizontal portions 5 and 6. In the wall in therecess adjacent the lower edge of the aperture'Q is an opening 7. In thewall 8 adjacent the upper edge of the aperture 2 is mounted a screw 9.In manufacturing the device l have found it desirable to cast this screwin place, thus avoiding the necessity of drilling and tapping the holein the Wall 8 in which the screw 9 is mounted. The socket supportingmember comprises a downwardly depending portion 10 of inverted truncatedconoidal contour and a circular lip 11. Two stud bolts 12 are cast inlugs formed in the socket supporting member and are adapted to hold inplace the porcelain socket 18, the latter being secured in place bymeans of s, 1925. Serial no. 1,155;

nuts let. In this way all necessity of drilling and tapping'holes forscrewsor bolts12is avoided. The socket supporting member provided'with alaterally etitenclingf'ln'glw,

which is fitted to andcoincide's with theV shaped portion 4' and thelateral ortions- 5 and6' of the recess 3, A slot 16' isforni'ed in thewall of the lug. and is fitted to a screw 17 mounted in' the hole '1'a'nutj 18 serving to hold the screw in position. I This slot o'bviously can be cast'in the"lug.15,' so there is no necessity of anymachine work uponit. I

provide a cover for' the socl'cet supporting member which" comprises" aconoida'l portion 19, which is provided with a'radially extending flangev 20, the outer edge of which is provided with" a" downwardly dependingflange 21, which extends down"beyondthetopof the lip 1101 the socketsupportingmeniber.

The periphery of' theflange 21isin'cl'ined' outwardly. A laterallyextending lug 22 is formed on the cover. This lug is provided with anupwardly extending" portion 23,

which has a slot 24; cast or formedtherein which isfitted to the screw9. rhave round it desirable in practice to form'should'ers '25 on thewall of the lug 23 adjacent theends of the wall forniingthesioreltoprevent the head'of the screw 9 from slipping off even if itwereslightly loosened; I H

The fixture "is assembled" in tliefo-llowing' n'ianner: p I

Screws 17 and'9 are loosely mounted in their places. The slot 16 inurewall of the lug 15 is inserted undentheihead' 'of the screw 17, when bytightening the nut 18, the lug 15 will be drawn into engagein'entwiththe shoulders of the recess3, so" that .it' is securely held fromdisplacement, and all that tliesc'rew' does is; to holdit from tippingdownwardly; The socket is is then placed upon the stud bolts 12 and thenuts 14. are tightened down drawing it into position. The lug 22 is thenpassed through the aperture 2 formed in the plate 1, and the walls 23are inserted underthe head of the screw 9, which passes into the slot24, until it is beyond the shoulders 25, when by tightening the screw 9it will tip the cover down causing a very tight fit between the lowersurface of the flange and the lip 11. In the preferred form illustrated,I provide a raised boss 30, which affords ample room for l 22, withoutcoming in contact with the wall of the building to which the fixture isattached.

The result of this construction is that the socket and wiring arecompletely enclosed, and consequently, water-proof. By projecting thefiange 21 beyond the lip 11, water is prevented from beating up into thesocketsustaining portion, and by providing for the slight inclination ofthe periphery of this flange, the water which is shed by the conoidalportion 19 will drip from the outer edge, thus providing additionalprotection against: the possibility oi the water reaching the interiorof the socket-sustaining member.

Most of the porch lights with which I am familiar have the holes for thesecuring screws arranged vertically which results in the fixtures beingalmost always out of plumb. I provide two holes 26 and 27 which are inthe same horizontal plane instead of vertical plane, so that by mountingthe screws 28 and 29 in them, there is no possibility of the bracketbeing twisted out of its proper position.

It will be apparent from the foregoing de scription that I haveeliminated all the necessity for high-grade machine labor on the bracketand yet produce a bracket which. is even more rigid in its constructionwhere the parts are screwed or fitted together by machine work; also,that I have provided a lighting fixture which is completely waterproofand may be used on the exterior of buildings without weather conditionscausing any trouble.

Although I have shown a specific form embodying my invention, it is tobe understood that this is only the preferred form and that I do notdesire to be understood as limiting myself to the specific details ofcon struction and configuration, except as such limitations shall appearin the hereinafter appended claims.

Having described my invention what I regard as new and desire to secureby Letters Patent is:

1. The combination with an apertured plate, of an outwardly extendingsocketsupporting member, there being a recess in said plate adjacent thelower side of said aperture, a bolt in said recess, a lug on said memberfitted to said recess, there being a slot in said lug which is engagedby said bolt, a cover for said member, a downwardly depending peripheralflange on said cover, a screw mounted in the said plate above saidaperture, a lug on said cover which extends through said aperture, therebeing a slot in said lug which engages said screw, shoulders on said lugadjacent said slot to prevent the head of the screw sliding off saidlug.

2. The combination with an apertured plate, of an outwardly extendingsocket-supporting member, there being a recess in said plate, saidrecess having a central V shaped portion and two laterally extendingportions, a lugs on said member fitted to said recess, a slot in saidlug, a bolt in said recess which holds said lug in said recess, a conoidal cover for said member, means mounted in said plate to hold said coverin position.

3. The combination with an apertnred plate, of an outwardly extendingsocket-supporting member, there being a recess in said plate, saidrecess having a central V shaped portion and two laterally extendingportions, a lug on said member fitted to said recess, a slot in saidlug, a bolt in said recess which holds said l-ug in said recess, aconoidal cover for said member, means mounted in said plate to hold saidcover in position, and means on said lug to prevent said securing meansbecoming disengaged.

4;. The combination with a plate having a raised boss thereon, therebeing an aperture in said boss, of an outwardly extendingsocket-supporting member, there being a recess in said plate adjacentthe lower side of said aperture, a bolt in said recess, a lug on saidmember fitted to said recess, there being a slot in said lug which isengaged by said bolt, a cover for said member, a downwardly dependedperipheral flange on said cover, a screw mounted in the said plate abovesaid aperture, a lug on said cover which extends through said aperture,there being a slot in said lug which engages said screw, shoulders onsaid lug adjacent said slot to prevent the head of the screw sliding offsaid lug.
